CUSTOMIZED DESIGNS
Typical automotive applications include Porous Self Lubricating Oil Bronze Bushing for wide range of linear motions, which include but not limited as windshield wipers, window mechanisms, seat adjusters, sun-roofs and fan motors. They can also be used in a variety of smaller electric motors and household actuators, in the consumer goods industry or in general mechanical engineering applications.
SINTERED BRONZE OIL BUSHINGS ADVANTAGE:
With no moving parts, Porous Self Lubricating Oil Bronze Bushing are the simplest type of bearing. Compared to ball and roller bearings, they generally handle higher temperatures and perform better in dirty environments. They are also intended by design to be self-lubricating, maintenance free and low cost.

DALON BUSHING FAQ:
Q: Bushing type selection?
A: The metallic structure of the self-lubricating bushing can be made from a wide range of bronze or iron based alloys. To select the proper material for a given application, it is necessary to check the maximum values of the material characteristics in comparison with:
Shaft linear speed - v
Applied load - p
pv (load x speed) factor
Shaft hardness and surface roughness and other parameters such as working
temperature and type of lubrication, etc.
Q: Lubricant Oil Selection?
A: Standard impregnating oil conforms to SAE 30 specifications
Lubricants are suitable for the temperature range from -40°C to 150°C
Also have option for customer to made special oil impregnation by self
Q: De-impregnation & Re-Impregnation?
A: De-impregnation required Degrease and wash in appropriate solvent
Eliminate the lubricant in a furnace heated around 400°C for 40 minutes under a neutral atmosphere such as N2, or with reducing agent such as N2 + H2
Re-Impregnation need Immerge during one hour the parts in an oil bath heated at a temperature between 60°C and 120°C, depending on oil viscosity.Then cool down in an oil bath back to room temperature. Finally drain and dry the self-lubricating bearings.
